  • Patent number: 8465453
    Abstract: Medical devices with surfaces on which viable biologic cells are magnetically attracted and retained are disclosed along with methods of magnetic coating. The medical devices can be located in a carrier liquid containing high concentrations of magnetic cells before or after implantation. The carrier liquid with magnetic cells may be contact with the medical device in vitro or in vivo. In either case, the carrier liquid may have a concentration of magnetic cells that is high enough to facilitate coating of the medical device within an acceptable period of time, e.g., several hours or less. Magnetization of medical devices before, during, and/or after implantation and apparatus for performing the same are disclosed. Degaussing of magnetic medical devices is also disclosed.

  • Patent number: 8465436
    Abstract: An implant centering system includes a sensor connected to a hollow cylindrical anchor via at least two struts. The hollow cylindrical anchor is transformable between a radially compressed configuration for delivery and a radially expanded configuration for lodging against a vessel wall. The struts longitudinally relocate the sensor between a first position in which the sensor is longitudinally spaced apart from the radially compressed anchor, and a second position in which the sensor is at least partially within a lumen of the radially expanded anchor and radially centered within vessel. In one embodiment, the struts are heat-set into a curved configuration and an externally applied force longitudinally relocates the sensor until the struts lock over center into their heat-set configuration. In another embodiment, radial expansion of the anchor longitudinally relocates the sensor without an externally applied force.

  • Patent number: 8454680
    Abstract: An endovascular conduit device and method for use during cardiac lead extraction and other vascular procedures is presented. The endovascular conduit device includes an outer-sheath, a conduit member, a lumen member, and an inflation member to control the flow of fluid within the conduit member. The endovascular conduit device may be positioned intravascularly as cardiac lead extraction or other procedures are performed. If necessary, as in the case of a vascular tear, the endovascular conduit device further includes expandable members that are activated to allow blood to be forced into the channel of the conduit member. Blood may then be contained and directed safely to bypass the area of vessel injury. In doing so, a catastrophic circulatory collapse or shock is prevented.

  • Publication number: 20120209370
    Abstract: A stentless support structure capable of being at least partly assembled in situ. The support structure comprises a braided tube that is very flexible and, when elongated, becomes very long and very small in diameter, thereby being capable of placement within a small diameter catheter. The support structure is preferably constructed of one or more thin strands of a super-elastic or shape memory material such as Nitinol. When released from the catheter, the support structure folds itself into a longitudinally compact configuration. The support structure thus gains significant strength as the number of folds increase. This radial strength obviates the need for a support stent. The support structure may include attachment points for a prosthetic valve.

  • Publication number: 20120197378
    Abstract: Systems and methods for delivering a medical device to a vessel within a mammalian body are provided. The medical device may have a tubular body with an interior and an exterior surface. A delivery device may include a balloon assembly having one or more balloons, with a proximal and portion with the medical device mounted thereon. When the balloon assembly is partially inflated the proximal portion has a larger diameter than the distal portion which may be inserted into the vessel. The proximal portion may have a sufficiently large diameter that prevents it from being inserted into the vessel and permits it to function as a stop. The balloon assembly may be further inflated to deploy the medical device within the vessel. The medical device diameter may expand and optionally contact the interior surface of the vessel when deployed. Alternatively, the invention may be configured to dilate tissue, without deploying a medical device.

  • Patent number: 8211160
    Abstract: A method for assembling a stent graft onto a balloon delivery catheter is disclosed. The method includes the steps of: assembling a graft over a stent with attached security rings and inserting the ends of the graft between the stent and the rings; placing the assembled stent graft on the delivery balloon of the delivery catheter; and crimping the stent graft onto the balloon. The stent may include a plurality of axially aligned belts that include a plurality of mid belts, and first and second end belts, where each of the mid belts includes a plurality of circumferentially spaced struts having first and second ends adjoining first sinusoidal-shaped elements, and each of the first and second end belts includes at least about twice the number of circumferentially spaced struts adjoining second sinusoidal-shaped elements. Also disclosed is a stent graft for use in practicing the method.

  • Patent number: 8152786
    Abstract: A catheter for collecting fluid such as blood from a vessel such as a coronary sinus of a patient has an elongated, flexible tubular portion and an annular sealing member spaced from a distal end of the tubular member. A proximal end of the tubular member is adapted to be connected to a source of suction for applying suction to a collection lumen of the tubular member. The distal end is placed in a blood vessel with the sealing member spaced from opposing surface of the vessel in an absence of a suction applied to the collection lumen. Suction is applied to the collection lumen in an amount sufficient to draw blood from the vessel through the fluid inlet and into the collection lumen and further sufficient to urge the opposing surface of the vessel to migrate into sealing engagement with the sealing member.

  • Patent number: 8147535
    Abstract: Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.
